Mathew Stanley Quay, born Sept.30,1833 at Dillsburg,York Co., PA. He married Agnes Barclay on Oct. 10,1855. They had two sons and three daughters. I am searching for a possible relationship thru marriage of one of the daughters into the West family. My father's name was Stanley Quay West.My West ancestors and Mathew Quay's settled originally in Chester County, PA.
